A virus might corrupt or delete data on your computer, use your e-mail program to spread itself to other computers, or even erase everything on your hard disk. See ‘What is a computer virus ?’

This new bug is distributed as an attachment to an e-mail message entitled, “I Love You.” If you open the attachment, the virus sends copies of the same e-mail to everyone listed in your address book. It then looks for files with .jpeg, .mp3, .mp2, .jpg, .js, .jse, .css, .wsh, .sct, and .hta extensions and overwrites them with itself, changing the extensions to .vbs or .vbe. These files must then be restored from backups- they cannot be retrieved or used again.
This virus traveled via e-mail messages entitled “I Love You,” crippling government and business computers in Asia, Europe, and the United States. No immediate cure was known as experts were stunned by the speed and wide reach of the virus.
According to computer security experts, the main operating systems infected include Windows 98 and Windows 2000 due to the fact that the virus was written in Visual Basic scripting language. Windows 95 and Windows NT 4.0 users could also be affected if they are using Microsoft’s Internet Explorer 5 Web browser[5].
